So any trace with a call to a bound method does not get optimized after the call. This is pretty bad...\n\n### Has this already been discussed elsewhere?\n\nNo response given\n\n### Links to previous discussion of this feature:\n\n_No response_\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-148457\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/Fidget-Spinner","@type":"Person","name":"Fidget-Spinner"},"datePublished":"2026-04-12T11:33:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/148438/cpython/issues/148438"}
